[Kyle, Gerardo, Chandra]
Removed 450 l/s turbo from 10" GV assembly on CP4 and replaced with blank and 1.5" valve + pump port. RGA is still attached and will remain in place as the newly designated "MY RGA." Next step is to get it on RGA network. Currently pumping down the small isolated volume with aux cart.
He leak checked GV11 annulus ion pump piping; currently pumping with aux cart and AIP. We started the process of opening GV11 by running motor to 900 rpm and back to 0, which mostly moves slack in system. But first we verified that the electrical leads were connected properly so the motor ran in the right direction. Looking down on pulley: CCW = closing. About one hour later we ran it up to 500 rpm and back to 0 which should start to pull the o-ring away from seal surface. Tomorrow we will run it up again to continue the process of very slowly opening GV11 as to not pull the o-ring out of the dovetail groove on gate.
Re-installed CP4 LN2 piping, sensing lines, and pressure transducer manifold as a means of storage.
We should be done with the "pancake" air compressor.
